hi,
I am having problems sampling multiple USB-6008 devices with one PC, can you help?
I am using C++ to configure multiple devices with the following header file
see attachment
I am then creating (up to) three objects with the following statements:
//create ADC input configuration (pass an ID number)
myAIConfig = new AIConfig(ID);
myAI = newAI();
myAI->configure(myAIConfig);
//start (short sample_frequency, int tbuf, short nchannels)
myAI->start(100, 1, NUM_CHANNELS);
The problem is that the first ADC provides a reading, but the 2nd and 3rd ADCs are buffering their data, and hence lagging behind changes in the voltages. The buffering increases with the sample frequency pointing to the fact that the buffer is being filled quicker and data is persisting, but i cannot reduce the time_buf variable to below 1 second. Is there a variable I am not setting, or is there another way I can remove the buffer?
Thanks for your help
Cheers, Marc
